: RCA Jack. Connect the control cable from the ACC terminal (or SEND,
TX GND etc.) of the transceiver. The center pin is to be shorted to
ground through the relay circuit of the transceiver. The DC current
necessary is 5V, 1mA only.
⑯ ⑯ ⑯ ⑯ ALC

ALC
ALC
: RCA Jack for ALC Voltage Output. Negative DC voltage appears at the
center pin, which is fed back to the ALC terminal of the transceiver.
ALC is used to keep the amplifier output power at certain limits. Also it
is useful when the transceiver output power is higher than 100W.
(See page 12, 8.ALC Connection). Also consult your HF/50MHz
transceiver's user manual.
